With the CPU being that slow, I don't think you'll really need a proper SSD. (And the CPU doesn't have the required PCIe interfaces anyway).
They probably could've added socketed RAM, but based on the photo, the main board looks quite full and messy with random chips (likely needed to work around CPU limitations), so it probably wasn't a high priority.
I'm interested in the cooling requirements and battery life.
I'm not interested in ARM CPUs with all their weird proprietary stuff.
